Implemented a complete tracking and attribution architecture for both mobile app and web platform, ensuring accurate conversion measurement and high-quality ad signal transmission. For the mobile app, I integrated Firebase SDK and connected it with GA4 to capture real-time in-app user events, session tracking, engagement funnels, and retention metrics. I also structured custom event parameters and conversion triggers to unlock deeper analytics visibility and future-proof the app for Meta SDK / Facebook CAPI integration. On the web side, I deployed a server-side tracking model using Google Tag Manager Server Container, enabling Google Ads Conversion Tracking and data routing to GA4 and Meta CAPI with enhanced event match quality. Instead of relying on basic browser-based tracking, I implemented secure server-side event forwarding using hashed user identifiers (email, IP, user agent), ensuring higher ROAS accuracy and reduced data loss caused by browser restrictions and ad blockers. This full-funnel tracking setup now allows the marketing team to run paid ads with clean signals, optimize conversion-based bidding strategies, and scale campaigns with confidence. With Firebase → GA4 → sGTM → Google Ads & Meta CAPI connected, the business now has a conversion-ready analytics infrastructure designed for high-performance advertising and attribution clarity.
